Access Controls

What are Access Controls?

Access controls are security measures designed to regulate who or what can view or use resources in a computing environment. They are essential for protecting data, systems, and networks from unauthorized access and ensuring that only authorized users have the necessary permissions to access specific resources.

Types of Access Controls:

Discretionary Access Control (DAC): Allows the owner of the resource to set policies defining who can access it.
Role-Based Access Control (RBAC): Permissions are assigned to roles rather than individual users. Users are then assigned roles, which grant them the permissions associated with those roles.
Attribute-Based Access Control (ABAC): Access rights are granted based on attributes (characteristics) of the user, the resource, and the environment. These attributes can include user identity, time of access, location, and resource sensitivity.

Components of Access Control Systems:

Authentication
Authorization
Accounting (Auditing)

Common Technologies for Implementing Access Controls

Firewalls - Regulate network traffic based on predetermined security rules.
Access Control Lists (ACL) - Lists that define which users or system processes are granted access to objects, as well as what operations are allowed on given objects.
Identity and Access Management (IAM) Systems - Frameworks that help organizations manage digital identities and control access to resources.
Single Sign-On (SSO) - Allows users to authenticate once and gain access to multiple systems without re-entering credentials.
